Second exemplary embodiment according to light fixture of the present invention is illustrated among Fig. 8-10.Be similar to first exemplary embodiment shown in Fig. 1-7, this of described light fixture second exemplary embodiment, integral body represents that with Reference numeral 101 its each primary clustering that has is: lamp casing 102; Spotlight 103; The bearing part 104 that is used for described spotlight; And shift mechanism 105, bearing part 104 is installed within the housing 102 by shift mechanism 105, and can be along line shifting in the displacement plane.In turn, bearing part 104 and spotlight 103 have formed spotlight device 110.In a single day further, make spotlight 103 be shifted along described direction of displacement so light fixture 101 is configured, then it produces and forces to pivot.
Being characterised in that especially of second exemplary embodiment: the displacement of spotlight 103 is not manual realization now, but the drive unit for this reason provide is provided and realizes.At first, for this purpose, light fixture 101 has single electro-motor, and this motor links to each other with axle spare 121 and it is driven or make its rotation.Axle part 121 longitudinal extensions are by lamp casing 102, and have external screw thread, thereby match with the corresponding internal thread of guiding sleeve 126 on being fastened to guide shoe 125.Can be understood that particularly as shown in Fig. 9 and Figure 10, guide shoe 125 has distolateral pin 127, its joint enters in the guiding groove 111 of guiding sleeve 109 of lamp casing 102.According to the direction that axle spare 121 is rotated by electro-motor 120, slide block 125 thereby move with one of possible opposite two directions of lamp casing 102.
Then, utilize another guiding groove 115 of the side-walls that is arranged on housing 102, realized the pivot in unison of spotlight 103 during the lengthwise movement of guide shoe 125.Pin 113 joints that are arranged on the bearing part 104 enter guiding groove 115, and according to the position of slide block 125 in lamp casing 102, correspondingly form the strong point at the bearing part 104 of spotlight 103.Bearing part 104 self is pivotably mounted on the slide block 125, causes thereupon, in case slide block 125 moves with possible opposite two directions, the spotlight 103 that then is secured to bearing part 104 is also pivoted in the mode that is fit to.Then, guiding groove 115 is constructed to make spotlight 103 to pivot between two maximum pivoted position, described two maximum pivoted position are always corresponding to the location of the end face that approaches lamp casing 102 of spotlight 103, thereby when spotlight 103 was in position, center (middle) in housing 102, spotlight 103 was vertically towards downside.
By spotlight 103 compatibly is suspended on the bearing part 104, spotlight 103 is pivoted around the second axis 117a, thereby also be provided with electric driver for this reason.For this purpose, light fixture 101 has another electro-motor 130, and it is connected to bearing part 104 and links to each other with gear 132 by cingulum 131, and gear 132 is with the fastened spotlight 103 that is connected to of the second pivot axis 117a.Like this, second electro-motor 130 allows spotlight 103 to pivot around the second pivot axis 117a in desirable mode.
Still shown in first exemplary embodiment, according to the invention has the advantages that: light fixture 101 has relatively low structure height, this be because, be converted to the specific pivot of the pivoting action of spotlight 103 by rectilinear motion, realized the pivot of spotlight 103 around the first pivot axis 106a with bearing part 104.But, electro- motor 120 and 130 the present permission of the use Long-distance Control at the spotlight position that will realize is regulated.This possible difficulty at visit light fixture 101 only is to have advantage especially under the applicable cases of its structure (arrangement).For example, in the ceiling room higher, can regulate the spotlight position like a cork by this structure apart from ground.
Special advantage of the present invention with reference to Figure 11-14, can be further explained.At first, Figure 11 a and Figure 11 b have correspondingly shown the spotlight light fixture 201 of conventional construction, wherein, illustration spotlight 203 vertically (Figure 11 a) and the behavior of spotlight 203 under the situation that axis pivots towards downside.According to the light fixture 201 shown in Figure 11 a and Figure 11 b, spotlight 203 correspondingly is installed within the housing 202, makes its outstanding slightly and its front side exceed the luminous opening 205 in center of lamp casing 202.Be parallel to the displacement of the basal surface of described housing, displacement for example provided by the present invention is impossible for this known light fixture.
Illustration from Figure 11 b can be understood that, the pivot of spotlight 203 on side direction causes the part 207 of the light that sent by spotlight 203 to be stopped by the lower cover 206 of lamp casing 202.In the example shown, can cause 25% light loss like this.
If spotlight is installed in the more top of lamp casing inside, make that it is outstanding and exceed the luminous opening of housing that the then light loss that is produced even can be bigger is shown in Figure 12 a and Figure 12 b when spotlight pivots.In this case, spotlight is at the structure of lamp casing lower cover even more unfavorable, makes that the major part of the light that sends is blocked (nearly 50%).
For spotlight light fixture 1 according to the present invention and 101, can realize by the displacement of spotlight 3 according to the present invention and 103 and the combination of pivot, but, spotlight 3 and 103 always is orientated in an identical manner at luminous opening 40 in center and 140 places, and described luminous opening is formed in the lower cover 41 and 141 of housing 2 and 102.Particularly, from the cross sectional view of Figure 13 a and Figure 13 b, can be understood that, even be in the pivot state shown in Figure 13 b, spotlight 3 and 103 also can be orientated and make the taper scope 42 and the 142 luminous openings 40 and 140 that can launch fully by lamp casing 2 and 102 of its light that sends.Embodied the clear superiority that surmounts traditional spotlight light fixture like this, this is because the orientation to spotlight 3 and 103 has multiple possibility now, and the risk of light loss can not occur.
Like this, by the invention provides a kind of spotlight light fixture, advantage is outstanding owing to have multiple adjusting possibility for it, and makes the optimization that at any time all can carry out spotlight harmonize.Meanwhile, guaranteed the flat structures of light fixture, this is because realize the corresponding adjustment of spotlight by adjusting device constructed according to the invention.At last, provide by Long-distance Control and realized the possibility that spotlight is regulated, in view of the above, further enlarged the possible range of application of described light fixture.
